Hi. We have an ivomec (ivermectin)/propylene glycol formula for ferrets at my clinic that I use with one of my fuzzies, Nicodemus. (This is my baby who loves medicine-used to climb my arm to try and get to Renate's meds, which she hated, when I drew them up, but won't eat the half a Heartgard tab...) The first time I tried to get him to eat it I had to break it into a million pieces and force them all into him, and he acted like I was killing him and got all stressed, so now he gets the liquid, which he loves for some reason-it's not even flavored! What a weirdo! I'll get the formula onto the list Tues when I get to work (it's a recipe for almost 30mL, but I divided the recipe by thirds b/c I only need it for one ferret at 1mL or so per dose, and it only lasts two years, so a full mix was too much)! -April [Posted in FML issue 3809]
